Learn vapor pressure definition and discover a few common examples which involve vapor pressure. Know and use formulas that involve the use of...
Under these conditions, the solute depresses the vapor pressure of the solution drop with the effect that solvent evaporates from the pure solvent drop and condenses onto the solution drop. The instrumentation detects the difference in temperature of the drops. Because colligative properties depend on...

Vapor pressure increases with increasing temperature. It decreases with the addition of a nonvolatile solute because the solvent constitutes a smaller proportion of the liquid, and the nonvolatile solute occupies space without contributing to vapor pressure. The greater the concentration of solute, the...
Three aspects of vapor pressure osmometry were examined: drop size, solute volatility, and the constancy of the calibration factor. It was shown that there is a drop size effect which is dependent on the solute concentration. Solutes having vapor pressures as low as 0.3 mm Hg under the ...
The vapor pressure of water at 20℃ is 2.338 kPa. If the solute in a solution made from 10.0 g of NaCl in 1.00 kg of water is 100% dissociated, what is the vapor pressure of the solution at 20℃? 相关知识点: 试题来源: 解析 解:$$ x _ { A } = \frac { \frac { 1 0 0 0...
on the number of solute particles that have been dissolved. The chemical nature of the solute is not important because the vapor pressure is merely a physical property of the solvent. The only requirement is that the solute only dissolved and does not undergo a chemical reaction with the ...
the most significant include volume changes due to evaporation and management of vapor pressure during pipetting steps. Rapid evaporation of solvent and concurrent increases in solute concentration due to high vapor pressure can be managed by lowering the temperature (and subsequent vapor pressure) of ...
Vapor pressure is a colligative property of solutions which means that its value depends on the amount of the solute in the solution. The lowering of...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your ...
The vapour pressure of pure liquid solvent 0.50 atm. When a non-volatile solute B is added to the solvent, its vapour pressure drops to 0.30 atm. Thus, mole fraction of the component B is View Solution The vapour pressure of pure solvent is 0.8 mm of Hg at a particular temperature. On...
